Abstract

The invention discloses a manufacturing method of a full-core reinforced composite template. The method comprises the following steps of 1, mixing materials, specifically, fully stirring and uniformly mixing phenolic resin, epoxy resin, melamine resin, benzoxazine resin, a curing agent, a release agent, a foaming agent and a diluent according to a formula; 2, infiltrating, specifically, fully infiltrating fiber reinforced materials with different varieties, specifications and gram weights through a glue dipping line tank, conducting heating and pre-curing through a drying tunnel to achieve the needed feeding amount and residual volatile matter, conducting cutting and stacking, and preparing intermediate prepregs with different varieties, specifications and gram weights; 3, conducting blank assembling, specifically, conducting blank assembling according to the density, thickness, size specification and strength requirements of the target product; and 4, conducting thickness limiting, heating, foaming, curing and molding through a hot press, inspecting, cutting, packaging and warehousing to obtain a full-core reinforced composite template product. The full-core reinforced composite template prepared by the method is light in weight, high in strength, flame-retardant, corrosion-resistant, homogeneous inside and outside, and free of structural defects. The manufacturing method is feasible and low in cost.

Description

technical field [0001] The invention relates to a method for manufacturing composite materials, in particular to a method for manufacturing a full-core reinforced composite template. Background technique [0002] The building formwork is a temporary support structure, which is manufactured according to the design requirements, so that the concrete structure and components are shaped according to the specified position and geometric size, maintain their correct positions, and bear the self-weight of the building formwork and the external load acting on it. Existing building formwork materials mainly include plywood, bamboo plywood, steel formwork, aluminum formwork, plastic formwork (including wood-plastic formwork and hollow plastic formwork) and the like. [0003] However, plywood has the problem of easy mold expansion due to water absorption, bamboo plywood is difficult to nail, and plastic formwork has the problem of poor weather resistance, so it is easy to be affected b...
